In a radiation detecting system including a first electrode which is imparted with a positive bias and permeable to a recording electromagnetic wave carrying thereon image information, a recording photoconductive layer which generates electric charges in response to receipt of projection of the recording electromagnetic wave, an organic polymer layer provided between the first electrode and the recording photoconductive layer, and a second electrode which is provided on the side of the recording photoconductive layer opposite to a side where the first electrode is provided and being for recording the image information by storing electric charges generated in the recording photoconductive layer upon projection of the recording electromagnetic wave, the organic polymer layer includes a hole blocking material.
